The best part is no one is forcing either trans down anyones throat. I think its great that we have options at least. I also will say that 10 sec. 1/4's, 200mph and 20 mpg are ALL within reach with a t56 with ONE rearend gear.
Mopar to the bone!!!

The argument of single or double OD for performance is sort of silly. 6th gear is so tall, it's for mileage and cruising, nothing else. If I'm driving my cars in anger, 6th is useless. Both of my cars top end in 5th gear, 6th is just too tall to overcome drag.
With more HP, 6th may become ueseful for sustained speed runs (though even in my 420 RWHP ZR-1 it's not), but then you start to run into the issue of ridiculous driveshaft speeds. If I'm building a car for high MPH, it'll be done with a big HP, a modest OD (not much taller than .75:1), and the correct rear gear to get it done.
Anyone who's ever driven a Viper with their 3.08 gears knows how useless 6th gear is when the car isn't geared for it. Both of my 6 speed cars have 3.42 gears, and even with 400+ HP and relatively light weight, they could use a little more gear.

Engine plays a role.
ears ago I was racing a Tbird Turbo Coupe down I25 in my 86 Daytona. At 125+ the engine could not pull hard enough in 5th to keep the Tbird behind me. Drop into 4th and I'd pull away from him.
Yes, absolutely engine plays a role. I was making my points with 4.6L EFI mods, which are plenty happy way up there in the RPM's, and sip gas with almost any throttle position. On a forum where most guys are playing with old school Mopar engines, often big ones, i shouldn't even have to make the argument for a 'more is more' OD.

But in all honesty there isn't a legal option for me to need double overdrive. Also, consider I drove my 64 300 from Memphis to San Diego with 4.10 gears doing 70 for most of it, so rpm does not bother me (A745 three speed in it).
I had a street racing buddy with a rather high-strung 289 Maverick who commuted one city over (20 miles) for years in that car. 4.30's, small rear tires. He'd very often drive the entire trip at 5000-5500RPM. I wouldn't even have believed it had i not been with him several times. To him burning the ridiculous amounts ov gas he did doing this was still cheaper than an OD (if he factored in his time - he was a mechanic, and the fact that he always spent 3X his budget to finish any simple job). He'd go through $500 a week in 87 octane gas. His engine loved the end ov the tach and he had nothing better to spend his money on.
We all love RPM, but honestly i think having to do that (or what you did) too often would keep most guys here from driving their cars. Maybe if gas was still as cheap as it was in the 80's...

Well, it was 92 when I made my trip. Super unleaded cost me $1.00/gallon most places, but the funny thing is my mileage was right around 15 for the whole trip. About the same as my wife's 05 Ram. What I liked best about this setup was that unless I was at a complete stop I could just leave it in third and go. Never could have done that with the Daytona.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

better shift quality?
I have never shifted a T56, but I have shifted plenty of rail shifters, they ain't better than a fresh A833 setup. When I got eh swap done in my 87 Diplomat I could shift with two fingers.
It's not the shift quaility when driving slow. Even the Fuller transmission in my Class 6 International Harvester truck can be shifted "easily" for a slow rpm matched shift.
We are talking about kicking the clutch and tugging on the shifter at full throttle. An 833 is similar to a truck transmission and a T56 is more like a dirt bike when it comes to finding gears while racing.
I've always thought the 833 shifted great. I think we just get used to (read: spoiled) by the utterly effortless and tiny throw ov a good aftermarket shifter on a modern trans. Going back to the old yeah... it does feel like a truck. Mr. Sox ov course might feel otherwise.
MY gripe with the 833 is the lack ov shifters to choose from. When i wanted to upgrade for an easier, faster, better shifter for my 4-speed i found a pile ov options that all seemed to do the same thing... replicate the factory shifter. Little details, a little better put together maybe... but nothing that really up-graded the design. As good as the factory shifter in a Mustang can be, an upgrade makes one hell ov a difference. Because no one i know bothers to think about these things and i had (at the time) no one to ask, i ended up buying a Super Shifter 3... because it was the best one i could buy that would use my pistol grip and not involve hacking. I've since heard some bad stuff about that one too. Still haven't installed it.

BTDT, not a problem with my freshly rebuilt A833 and new Hurst shifter. Never missed a shift, never had an issue with it being other than right shifting. Now if it were all wore out and had a sloppy shifter, then yeah it's a PITA. But that's true of anything.

This has nothing to do with Ronnie Sox's ability to shift a truck like 833 or your ability to not miss a shift in an 833.
I'm a huge Mopar fan and will defend an 833 for strength anyday but the fact is a T56 is EASIER to shift fast than an 833.
Go drive one before you get offended over my opinion on the 833.

There is hardly any throw in my Cobra T-56. But, the design is so much different from the old 833. It is like night and day.

That will be a cool combo. Is this based on the yellow 340 car you just picked up?
